[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0021] Please see the attached Figure 1-3 The toothbrush cutting machine of this embodiment comprises a frame 1, on which two groups of symmetrically distributed belt conveyors are rotatably connected, a support block 2 is provided between the two groups of belt conveyors, the support block 2 is fixedly connected to the frame 1, a guide groove 3 is provided on the support block 2, and toothbrush cutters are provided on both sides of the guide groove 3. The toothbrush cutter is rotatably connected to the frame, a waste trough 4 is fixedly connected to the frame, the waste trough 4 is located below the guide groove 3, and a hopper 5 is provided below the waste trough 4; the belt conveyor comprises an upper belt 6 and a lower belt 7, the upper belt 6 is provided with a toothbrush cutter. It is equipped with an upper driving wheel 8 and an upper driven wheel 9, which are rotatably connected to the frame. The lower belt 7 is equipped with a lower driving wheel 10 and a lower driven wheel 11, which are rotatably connected to the frame. The upper driving wheel 8 and the lower driving wheel 10 rotate in opposite directions, and a conveying channel is formed between the upper belt 6 and the lower belt 7; the toothbrush cutter includes an upper cutter 12 and a lower cutter 13, which rotate in opposite directions, and the outer contour of the upper cutter 12 is tangent to the outer contour of the lower cutter 13.
[0022] The toothbrush blank is stuck in the gap between the upper belt 6 and the lower belt 7, and the friction force of the upper belt 6 and the lower belt 7 on the toothbrush blank is driven to move from the left side to the right side of the frame. A downwardly protruding card block is provided between the toothbrush blanks, and a guide groove 3 is provided on the support block 2 of the frame to guide the card block. The toothbrush blank moves to the right along the guide groove 3. When the toothbrush blank moves to the toothbrush blank, the toothbrush blank moves to the right. When the toothbrush cutter is in the position, the two groups of toothbrush cutters cut the connection parts of the two toothbrushes connected at the ends respectively, so that the two connected toothbrushes are divided into two independent parts. There are two groups of toothbrush cutters. The upper cutter 12 and the lower cutter 13 of the toothbrush cutter are located on the inner side of the upper belt 6 and the lower belt 7. The rotation of the upper cutter 12 and the lower cutter 13 will not collide with the upper belt 6 and the lower belt 7. After the toothbrush blank is cut, the upper belt 6 and the lower belt 7 still drive the toothbrush to move to the right. The residue in the guide groove 3 continues to move to the right along the guide groove 3 under the action of the left toothbrush blank. When the toothbrush and the residue move to the rightmost side of the frame, the food leaves the guide groove 3 and enters the distributing trough. The cut toothbrush leaves the upper belt 6 and the lower belt 7 under the action of inertia and falls into the hopper 5. The width of the waste trough 4 is less than the distance between the two belt conveyors. In order to facilitate the falling of the waste, the width of the waste trough 4 is greater than the width of the distributing.
[0023] The bottom of the lower belt 7 is supported by a fixed plate of the frame 1 to keep the upper belt 6 taut. An upper pressure plate 14 is installed on the inner side of the upper belt 6. The upper pressure plate 14 exerts a downward force on the lower half of the upper belt 6 to ensure that the bottom of the upper belt 6 can contact the toothbrush blank and prevent the upper belt 6 from loosening.
[0024] The synchronous pulley 17 includes a stepper motor, a connecting belt and three connecting wheels, one of the three connecting wheels is fixedly connected to the stepper motor, one is fixedly connected to the lower belt gear 15, and one is fixedly connected to the lower cutter gear 18. When the stepper motor works, the lower cutter gear 18 and the lower belt gear 15 are driven to rotate together through the action of the connecting belt and the three connecting wheels, wherein the lower belt gear 15, the upper belt gear 16, the lower cutter gear 18 and the upper cutter gear 19 have the same module, and the belt conveyor and the toothbrush cutter are driven to move synchronously through the synchronous pulley 17.
[0025] The waste chute 4 is tilted downward, and the residual materials dropped into the waste chute 4 fall downward under the action of their own gravity.
[0026] A push plate 21 and a pushing cylinder 20 are provided on the left side of the hopper 5. When the hopper 5 is filled to a certain amount, the toothbrushes in the hopper 5 are pushed out by the pushing cylinder 20 to avoid too many toothbrushes being scattered around and to increase the collection speed of the toothbrushes.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
